IDCS Data Capture System - To reduce product give-away

More Information on IDCS Data Capture System

The IDCS collects data from every pack that has passed through your Ishida checkweigher and integrated metal detectors, generating dynamic, graphic displays and reports with a wide range of profitable uses.

The system provides all the information you need to reduce giveaway and downtime to increase efficiency (including Overall Equipment Efficiency, OEE), making a real and lasting contribution to your production line.

The capabilities of the system include live display of losses through overfilling, presented as pounds sterling or euros; presentation of incentive schemes to motivate shop floor staff as they interact with the device; data collection that can identify whether training or equipment adjustments are needed.
